Bussmann Bullet™ ECSR150 Current Limiting Time Delay Fuse, 150 A, 600 V, 200 kA Interrupt, RK5 Class, Bullet/Cylindrical Body

Short Description

ECNR/ECSR dual element fuses are recommended for AC power distribution system mains, feeders and branch circuits having inductive loads (motors, transformers) or non-inductive loads (lighting, heating) where the available short circuit current does not exceed 200000 RMS symmetrical amperes. These dual element, time delay fuses have minimum industry standard time delay of 10 s at 5 times the fuse rating (8 s minimum for 250 VAC, 30 A and less). The time delay characteristics of these fuses typically allows them to be sized closer to the running ampacity of inductive loads to reduce cost and provide improved over current protection. These fuses will override normal equipment current surges to reduce unnecessary fuse openings. They are the most popular fuses used in the industry and the most economical for most applications, especially motors and transformers. They have moderate current limitation.

Features
  • True dual element construction allows sizing of 125% FLA for motor backup protection
  • Superior overload and cycling capabilities
  • Current limiting provides component short circuit protection
  • Provides motor overload, ground fault and short circuit protection
  • Provides a good deg of short circuit protection (greater current limitation) to help protect downstream components from high fault currents
  • The time delay feature makes it possible to use fuse amp ratings, which are much smaller than those of non-time delay fuses
  • Considerable cost savings occur by permitting the use of smaller size switches, panels and fuses themselves
  • Helps protect motors against burnout from overloads and single phasing when sized properly
  • Gives motor running back-up protection to motors without extra cost
